Chelsea and Wrexham booked their respective places in the fifth round of the FA Cup with wins on Friday over Hull City and Ipswich Town, respectively.

No real surprises on Friday, but we won't put it past Saturday to serve us some shocks; after all, this is what the ancient FA Cup is typically known for. We cannot wait to see what the rest of the weekend holds for the competition.

Struggling Premier League club West Ham will travel to Burton Albion in search of a fifth-round ticket. It's a conundrum for the Hammers, as they would be better off without distractions; however, their fans need some feel-good factor, while the players need something to keep the momentum going after the draw against United.

Burnley is in the same boat. The Clarets host sixth-tier club Mansfield on Saturday. Scott Parker's side may have resigned to fate in the league, but a game against giant-killing Mansfield—the team that bundled out the holders in the 3rd round—could be tricky.

Manchester City put 10 past their opponents in the 3rd round; they have another lower-tier club in the 4th round. Are we expecting loads of goals against Salford at the Etihad on Saturday? It's clearly a baptism of fire for Salford. Good luck to them.

It's a game of huge significance at St. Mary's Stadium on Saturday. Both sides met in the league earlier in the week, with Southampton coming from three goals down to beat Leicester City 4-3 at the King Power Stadium. They go again. Can the Foxes respond this time?

Aston Villa faces Newcastle at Villa Park on Saturday. Both sides have real reasons to go for this. There's no real chance for Villa to win the Premier League; you sense that at some points, Unai Emery needs to land a title at Villa Park. The FA Cup is a big opportunity for him to achieve that.

Finally, on Saturday, it's the turn of the Premier League champions, Liverpool, to take on Brighton. Fabian Hurzeler spoke of his disappointment after the Seagulls lost midweek in the league. They need a response away at Liverpool; it should be fun.
